Ex-President George H.W. Bush was in a Houston hospital Thursday for treatment of a lingering cough. Bush, 88, has been in and out of the hospital recently for complications resulting from bronchitis, Methodist Hospital said in a brief statement. Jean Becker, Bush’s chief of staff in Houston, told the Houston Chronicle his most recent stay began Friday.

Bush spokesman Jim McGrath told CNN that his family hopes he will be discharged by the weekend.
